Purpose of ResearchPurpose of Research

• The purpose of this research effort is to determine if:

• the output of the BI System sufficiently balances information quality, quantity, and availability

• delivers the right information, to the right people, at the right time

• enabling quality decisions in high velocity environments.

Relevant Literature and flow to the DVRelevant Literature and flow to the DV

High Velocity Environment Faster decision = better performance

Type of information most needed in high velocity environments is real time information. This need drives

the decision to implement a real time Business Intelligence System

Enough info to make decision without information overload. Measured

by Number of Alternatives

Research QuestionsResearch Questions

Research Question 1:

Do BI Systems enable faster and better decisions in High Velocity Environments, or are decision speed and decision quality inversely related?

Eisenhardt and Bourgeois, 1989; Bogner and Barr, 2000; Judge and Miller, 1995; Baum and Wally, 2003.

Research Design and MethodologyResearch Design and Methodology

• To empirically measure effect size of associations between the variables, constructs will be tested using Structural Equation Modeling (SEM).

• Survey is hosted on Zoomerang.com. Participants are solicited using Linked-In User Groups.

Population and SamplePopulation and Sample

04/13/23 17

•The population under study are those who employ Business Intelligence Systems to aid in rapid decision making in High Velocity Environments.

•Research indicates an adequate sample size for CFA based SEMs is 150 (Ding, Velicer, and Harlow (1995); Anderson and Gerbring, 1998); Muthen and Muthen, 2002).

Based on the recommendations of previous SEM research, the sample size desired for this study is 300, with a minimum acceptance of 150.

–It is estimated that a minimum of 1500 surveys must be send to yield the desired sample size of 300.

Research ContributionsResearch Contributions

This study has both theoretical and practical implications.

• First, from the theoretical perspective, this study contributes to IS and Decision Science literature by pulling topics from each together into a cohesive set of dependent and influencing relationships. Decision theory is a mature area of research that has shaped the development of decision support systems. Understanding the value of decision support systems as they grow and evolve with technological advances is important to the continued development of information systems sciences. .

• Second, this study enhances our understanding about the value of BI Systems as a decision aid, which may prove beneficial to organizations considering adoption and investment in a BI System. The outcome of this research will extend the knowledge of BIS within the information systems community.

Variables Hypotheses

Decision QualityDependent Variable

Decision quality is the Dependent Variable

Decision Speed H1: When enabled with a Business Intelligence System, Decision quality is positively associated to decision speed.

System UsageIndependent Variable

H2: Higher BI system usage is positively associated to greater information availability.H3: Higher BI System Usage reduces information overload.H4: Higher BI System Usage is positively related to information quality.

Information Overload Mediating Variable

H5: BI aided groups will consider a greater number of simultaneous alternatives than non BI aided groups.H6: The number of alternatives is inversely related to the decision speed. H7: The number of alternatives is positively related to the decision quality.

Information AvailabilityMediating Variable

H8: Information availability is positively associated with decision speed.

Information QualityMediating Variable

H9: The quality of the information is positively associated with decision effectiveness.
